A fundamental problem in radar system design is the choice of transmit waveform and receiver processing for detecting targets of interest. There exist well-defined information theoretic methods in the published literature that describe how to design waveforms and receivers for optimal target detection in given noise/clutter Power Spectral Densties (PSDs) [1]}, [2]}, [3]}, [4]}, [5]}, [6]}. Using a transmit energy constraint, these methods detail the structure of the magnitude square of the waveform's spectrum, also known as the Energy Spectral Density (ESD). Such waveform design methods have demonstrated clear improvement in detection performance compared to waveforms with a flat ESD such as the Linear Frequency Modulated (LFM) waveform [4]}, [5]}. The improved detection performance of these Matched Illumination (MI) waveforms over flat spectrum waveforms is especially noticeable in scenarios where there is limited available transmit energy and the noise/clutter PSDs vary widely in magnitude across the operational band of frequencies [5]}.
